摘要
格鲁吉亚卡杜里电站从两条河流分别取水,通过两条不同长度的引水支洞汇入主洞,是跨流域引水式电站。针对该电站引水系统取水水位不同,支洞长度不同,支洞汇入点水流复杂的问题,采用特征线法建立了水力过渡过程计算的数学模型,计算得到调压室在最不利工况时的最高、最低涌波水位,并与模型试验结果进行了比较,两者吻合性好。建立的复杂引水系统的数学模型对开发跨流域引水式电站具有理论指导意义和实际应用前景。
Khadori power station in Georgia with a transbasin diversion system take water from two rivers. The two braach tunnels have different length, which confluence into main tunnel. This paper analyses characteristics of the diversion system, such as different water level of upstream, different length of branch tunnel and complex flow at branch tunnel junction. Numerical simulation is set up by the method of characteristics. It solves the highest and the lowest water level of fluctuating in surge chamber at the most disadvantagous conditions. The results of numerical simulation are similar to which of model tests. The numerical simulation model set up in this paper is conducive to develop power station with the transbasin diversion system.
